A plague of locusts...

It's not really a plague.... more like two or three a day for the last week, but I have to chase them around and catch them in a jar, which is a major hassle, so I'm calling it a plague. Our beroom has a balcony and in summer the door is open all the time. There are some trees outside and I guess they go there first and then see the open window and decide to fly in. Or maybe not. I don't know.... Why would they want to come into the house when there's all that greenery outside? Seems a bit daft to me...
